VALVE.

To all whom it may concern:

Be it known that I, VLADIMIR V. ,Mnssnn, a citizen of the United Statesresiding at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Valve, of which the followingis a specification.

This invention relates to a device for controlling the flow of waterfrom an irrigation or other water system and more particularly to avalve of the vertically movable type, and one of the main objects of theinvention is to produce a valve of the class described provided with agate which may be readily raised or lowered and retained in any desiredposition by a single operating means.

Another object of the invention is to produce a device of the characterdescribed, of,

economical and simple construction.

Other objects and advantages will appear hereinafter from the followingspecification. a

Referring to the drawings, which are for illustrative purposes only:Figure 1 is an elevation showing the outer side of the valve with thegate in closed position. Fig. 2 is a view similar to Fig. 1, showing thegate in raised or open position. Fig. 3 is a vertical sectional view online m 00 Fig. 1. Fig. {L is a horizontal sectional view on line w m*Fig. 1. Fig. 5 is a vertical sectional view through a portion of thegate or closure member. Fig. 6 is a perspective view of thenon-revoluble nut forming part of the operating mechanism. Fig. 7 is aperspective view of a cross-head or carrier.

The valve consists of a stationary memher 1 formed in the presentinstance of cast iron and consisting of a plate 2 having a centralopening 3, and an annular flange 4: projecting inwardly therefrom forthe purpose of affording fastening means to the pipe or flume on whichthe valve is used. Formed around the edge of the central opening 3 is anannular flange 5 forming a valve seat for the gate or closure member 6.The gate 6 in the present instance is circular in form and is providedon its inner face with an annular groove 7 in which is seated a gasket8. The groove 7 is so placed in the face of the gate 6 that the gasket 8is adapted to be seated on the annular flange or seat 5 on thestationary member 1.

Projecting outwardly from the gate 6 is a Specification of LettersPatent.

hollow extension :9 having side walls 10 and an outer wall 11 connectingthe two side walls. The extension 9 on the gate 6 is received in acentral opening 12formed in a cross-head 13. The: cross-head 13 isprovided at each. end with. a tongue 14 adapted to be received byvertical guides formed on the stationary member 1 and consisting ofextensions 15terminatingalong their outer edge in flanges 16. The-upperand lower bars 17 of the cross-head 13 are each provided with acentralbore 18 for receiving shouldered collars 19 which form'bearingsfor .a vertical square operating shaft or rod 20 which is secured toithecollars 19; by means of pins 21.

Between the upper. and lowerbars 1'7 of the cross-head 13 in the centralopening 12 heretofore referred to, is a screw-member 22 having .a squarebore longitudinally disposed therethrough, through which the squareoperating shaft 20 passes. Threaded on the screw member. 22;. is anon-revoluble nut of brass 23, provided on zthe opposite sides thereofwith inclined lugs or extensions 24 adapted to bear against the walls ofinclined grooves 25 formed in the walls of the extension 9 on the gate6, the length of the nonrevoluble .nut 23 being .shorter -than thedistance between the'upper and lower bars 17 of the cross-head13.

The gate6 is provided at'its lower edge witha projection or lug 27 whichis adapted to strike and rest upon a stop or lug 28 on the stationarymember-1 when the gate 6 is in lowered or closed position for thepurposeof supporting the weight of the movable parts of the valve and at thesame time position the gate. 6 over-the seat 5 onzthe stationary member1, so that the gasket 8 is in proper relation to the. seat 5.. The. operating shaft or bar 20 is provided at its upper .end with. operatingmeans consisting of a causing the nut, which being non-revoluble, totravel along the screw member 22 into its lower position shown in Fig.3. The grooves 25 in the sides of the extension 9 on the gate 6 being inengagement with the lugs 24 on the side of the nut 23 andv the groovesbeing inclined, cause the extension 9 and the gate 6 to move laterallyin relation to the operating shaft 20, thereby clamping the gate 6against its seat 5 on the stationary member 1, and causing thecross-head 13 to .bear against the flanges 16 on the guides of thestationary member 1. When it is desired to change the position of thegate 6 for the purpose of opening the same, the operating shaft 20 isturned in the reverse direction from that heretofore described in theoperation of closing the gate, which action causes the non-revoluble nut23 to ride upwardly on the screw member 22, thereby forcing the gate tomove toward the operating shaft 20 and away from its seat 5, due to theaction of the lugs 24 on the nut 23 traveling in the in clined grooves25 in the extension formed on the gate 6. When this action has takenplace, the operating bar 20 may be lifted bodily, vertically, therebyraising the crosshead 13 in the guides on the stationary member 1 andcarrying therewith the valve gate 6 as the extension on the valve gate 6is confined between the upper and lower bar of the cross-head 13. Whenthe'gate 6 is raised to the position desired, the operating bar or shaft20 is turned, as heretofore described, in the direction to produce theclamping action heretofore described.

What I claim is:

1. A valve comprising a stationary member having an outlet openingtherein, a seat on said member about said opening, guides on saidstationary member, a cross-head movable in said guides, a closure membercarried on said cross-head, and having inclined grooves, a threadedshaft, a non-revoluble nut on the shaft, having inclined lugs engagingthe inclined grooves of the closure member for moving said closuremember laterally from said cross-head against said seat.

Copies of this patent may be obtained for five cents each, by addressingthe (Commissioner of Patents,

2. Avalve comprising a stationary member having an outlet openingtherein, a seat on said member about said opening, extensions on saidstationary member, flanges on said extensions, a cross-head movable insaid extensions on the closure member on the inner side of said flanges,an extension on said closure member extending into said cross-head, andhaving inclined groo ves, a threaded shaft, a non-revoluble nut on theshaft, having inclined lugs engaging the inclined grooves of the closuremember to on the stationary member.

8. A valve comprising a stationary member having an outlet openingtherein, a seat on said member about said opening, guides on saidstationary member, a crosshead movable in said guides, a closure member,a hollow extension on said closure member extending into said cross-headand having inclined grooves therein, an operating shaft extendingthrough said extension, a screw member on said operating shaft, anon-revoluble nut on said screw member, and lugs on said nut extendinginto the grooves in the extension on the closure member.

4. A valve comprising a stationary member having an outlet openingtherein, a seat on said member about said opening, guides on saidstationary member, flanges on the ,outer edges of said guides, across-head movable in said guides against said flanges, a closuremember, a hollow extension on said closure member provided with inclinedgrooves on its inner face, an operating shaft extending through saidhollow extension, a screw member fast to said operating shaft, anon-revoluble nut on said screw member, and lugs on said nut extendinginto the grooves in the hollow extension on the gate.
